Let me reiterate my thoughts.
First of all, I have a wording error, which I would like to correct.
What I meant by "tip" is correctly "button".
What I need is a shortcut to [ remove color button ] or its menu command.
Arrangement of buttons
Function of buttons
These are as they are now.
The reason these three buttons are different from Adobe products is that the developers have not yet reached a conclusion.
For example, there are unresolved issues such as what kind of typicality should be derived for gradients.
This is that of Adobe products.
This layout has been maintained for more than 30 years now.
Some people may never have used it. It may need to be revisited to see if it works for many people.
As for the gradient button, this button might have been effective in the 1990s when this feature was still rare. Today, however, gradients can be created in other UIs.
Whether or not to use these buttons depends on the position of the creator and the nature of the work.
Those who are called DTP operators may use them more often than those who are creative artists.
This is the case when working in a situation where instructions and materials are given. In these tasks, they often work while checking the fill and stroke of an object. I habitually use remove color & undo a lot.
In the days when there was no layer function, I used it frequently to remove the full view to see the background.

I guess you could say this is my habit. When I start working with the pen tool, I first set fill to no fill and stroke to black. This could be preset, but for various reasons, I try not to create many presets.
After that, when I do some other work and pick up the pen tool again, I start writing with no fill.
I have written about gradients before.
